INTRODUCTION

In this tutorial, we are testing the speed of a DC motor using a 12-40v 10A Power DC Motor Speed Controller.

HARDWARE REQUIRED

• DC 12V DC 40V DC Motor Speed Controller – 1
• 100 RPM DC Motor – 1
• 12V DC Adapter – 1
• Gear Wheel -1
• Hook Up Wire 1mt – 1

SPECIFICATIONS

DC Motor Speed Controller:

• Working Voltage: DC 12V DC 40V
• Control Power: 0.01 400W
• Static Current: 0.02 A ( Standby )
• PWM Duty Cycle: 10% -100%
• PWM Frequency: 13 kHz
• Control the speed of a DC motor with this controller
• High efficiency, high torque, low heat generating
• With reverse polarity protection, high current protection

The 10A fuse with the reverse connection of the power supply and control voltage over-voltage protection function can adjust the speed by the external 0-5V signal

Note: This can not be used for the brushless motor.

The controller is NOT reverse-polarity protected and will be damaged if it connects the supply voltage with the wrong polarity. Double-check all connections before applying power and always turn off the power supply before making any wiring changes.

CIRCUIT CONNECTION

• First, connect the dc motor negative positive to the knob connection point.
• Fix a gear wheel on the motor and fix it with the screwdriver.
• Now connect the 12v.1amp adapter for the power supply of the controller and switch on the power and turn the knob you will see the speed variation on the wheel.
• You can check the voltage rating using a multimeter. Connect the positive wire of the multimeter to the red wire of the motor and similarly connect the black wire of the multimeter to the DC motor black wire.

WORKING AND OUTPUT

Rotate the potentiometer and you can control the speed of the motor.
